java - 有没有maven sleep 功能？

Question

我有 maven 配置文件集用于测试，在预集成测试中，maven 启动两个 jetty 服务器，然后开始测试。我偶然发现的问题是在服务器中，测试开始时它们没有完全加载。似乎通过在测试中添加 5 秒 sleep 时间来解决问题，但我希望将其添加到 Maven 中并从测试中删除。无论如何我可以这样做吗？请查看下面的代码示例以获取更多信息

Answer 1

您可以借助 maven antrun 插件来完成。像这样:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <configuration>
        <tasks>
            <sleep seconds="5" />
        </tasks>
    </configuration>
    <executions>
        <execution>
            <id>sleep-for-a-while</id>
            <phase>pre-integration-test</phase>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>

编辑:以防有人发现这一点。根据 jl 的评论，任务确实已被弃用，这里是基于使用目标的同一件事。稍微重组但具有相同的功能。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <id>sleep-for-a-while</id>
            <phase>pre-integration-test</phase>
            <configuration>
                <target>
                    <sleep seconds="5" />
                </target>
            </configuration>
            <goals>
                <goal>run</goal>
            </goals>
        </execution>
    </executions>
</plugin>
